Abstract
Zinc Oxide (ZnO) nanoparticles were synthesized by hydrothermal method and analyzed for various properties. Analysis of the XRD spectra of the synthesized nanoparticles showed 46 % crystalline zincite and the average grain size was calculated to be around 39.63 nm, studies of the FTIR spectra measured over the range between 4000–500cm−1 proved the presence of Zn Obonding of the synthesized nanoparticles at 734.26 to 1473.71 cm1 .SEMimage of the synthesized nano particles showed the formation of agglomerated nanoparticles of different shapes whose size are within the nanometer range while, cyclic voltamo gram of the immobilized ZnO nanoparticles on GCE also showed significant increase in redox peak current when compared to the bare (unimmobilized) GCE. It can be concluded from the obtained results that ZnO nanoparticles have been successfully produced which can be used to improve the performance of electrochemical sensors.
